Fish and Aquatic Life
Hartford Millpond, in the Rubicon River Watershed, is a 9.69 acre lake that falls in Washington County. This lake is managed for fishing and swimming and is currently not considered impaired.

A small elongate impoundment of the Rubicon River in Hartford, created originally for waterpower to operate a flour mill. Managed as a children's fishing pond, with a large population of carp and panfish. Ample public access is afforded by a city park of 10.5 acres three city streets, and navigable water. Major use problems are winterkill, weeds, carp, and fluctuating water levels. The pond is entirely within the City limits, and has very little value for waterfowl and fur bearers.

Wisconsin has over 84,000 miles of streams, 15,000 lakes and milllions of acres of wetlands. Assessing the condition of this vast amount of water is challenging. The state's water monitoring program uses a media-based, cross-program approach to analyze water condition. An updated monitoring strategy (2015-2020) is now available. Compliance with Clean Water Act fishable, swimmable standards are located in the Executive Summary of Water Condition in 2018. See also the 'monitoring and projects' tab.
Phase 3 of Lake Classification Project. Public Hearing and Ordinance revision adoption for the lakes in Washington County. Dissemination of proposed ordinance changes to the other local units of government. Enforcement of revised zoning provisions related to shorelands, wetlands, and floodlands through current channels. Information to public of changes in Washington County codes by meetings, publicity, pamphlets, and brochures.
Through this project Washington County will develop a waterbody classification system; review and revise shoreland-wetland and floodplain ordinances; and refine the ordinance provisions governing shorelands, wetlands and floodlands, incorporating the waterbody classification into them.
Wisconsin's Water Quality Standards provide qualitative and quantitative goals for waters that are protective of Fishable, Swimmable conditions [Learn more]. Waters that do not meet water quality standards are considered impaired and restoration actions are planned and carried out until the water is once again fishable and swimmable
Management goals can include creation or implementation of a Total Maximum Daily Load analysis, a Nine Key Element Plan, or other restoration work, education and outreach and more. If specific recommendations exist for this water, they will be displayed below online.
Monitoring the condition of a river, stream, or lake includes gathering physical, chemical, biological, and habitat data. Comprehensive studies often gather all these parameters in great detail, while lighter assessment events will involve sampling physical, chemical and biological data such as macroinvertebrates. Aquatic macroinvertebrates and fish communities integrate watershed or catchment condition, providing great insight into overall ecosystem health. Chemical and habitat parameters tell researchers more about human induced problems including contaminated runoff, point source dischargers, or habitat issues that foster or limit the potential of aquatic communities to thrive in a given area. Wisconsin's Water Monitoring Strategy was recenty updated.

Hartford Millpond is located in the Rubicon River watershed which is 79.15 mi². Land use in the watershed is primarily agricultural (45.10%), grassland (19.90%) and a mix of wetland (13.40%) and other uses (21.60%). This watershed has 127.08 stream miles, 592.86 lake acres and 6,453.66 wetland acres.
Nonpoint Source Characteristics
This watershed is ranked Medium for runoff impacts on streams, Not Ranked for runoff impacts on lakes and High for runoff impacts on groundwater and therefore has an overall rank of High. This value can be used in ranking the watershed or individual waterbodies for grant funding under state and county programs.However, all waters are affected by diffuse pollutant sources regardless of initial water quality. Applications for specific runoff projects under state or county grant programs may be pursued. For more information, go to surface water program grants.
